HARVESTER The Schedule referredlto in these Letters Patentauti making part 0f the Same.

To. all whom lit may concern `Be it known that I, Anios RANK, 'of Salem, in the county of Columbiana, and State of Ohio, have invented certain new and useful Improvements in Harvesters, of which the following is a full, clear, and exact description. l f

Theinveniiou herein claimed relates to the devices for discharging theY cui grain from the/platformfin gavels, and constitutes :in improvement on the invention shown in Letters Patent bf the United. States, No. 88,209, granted to me March 23, 1869.

The object of the first part of the invention is so to construct the machine that a rear-delivery or a side-delivery dropper may readily be applied thereto,

to which end the improvement consists- First, of the combination, with the finger-beam, of platform-sections, turning on axes transverse to the finger-beam, supported on brackets connected at their front ends with a rocking-bar, contiguous to and parallel with the finger-beam, and inserted in sockets or lugs on the finger-beam, the brackets extending forward of the bar and under the finger-'beam to prevent the sagging of the platform-sections, as hereinafter set forth.

The object of the next part of 4my .invention is to dispense with the separating-rod or cut-oli` used in droppers, andthe improvements consist- Second, of the combination of an oscillating grating on the divider'slde of the platform, with a series of toothed or slatted overlapping platform-sections, turningon axes transverse to the finger-beam, which sections successively rock in their bearings to discharge the gavel, and then, by areverse movement, convey the grain which has fallen dln-ing this discharge to the divider or grain-side of the platform', and deposit it on an oscillating grating, turning on an axis parallel with that of the platform-sections, from which grating the grain is removed at the commencement of the next discharge.

Third, the improvement further consists of the combination of the vibrating grating with the adjacent platform-section, by means of cranks and a slotted link, which secures their proper relative movements.

The object of the next part of the invention is to preserve the rakes or platform-sections in their proper relation to each other, and the improvement consists- Fourth, of the combination of oscillating platformsections, andan oscillating receivinggrating, with'a connecting-bar supporting their rear ends.

Fifth, the improvement further consists of a grating or clearing-rake, vibrating on an axis transverse to the finger-beam, and located at the divider or, grain-end of the platform.

In the accompanying drawings, all the improvements herein claimed are shown, as embodied in a machine similar to that shown in my patent of March 23, 1869, hereinbefore mentioned. Y,It will, therefore, be

vunnecessary here to describe, in detail, the construetion of the machine. I

Figure l represents a plan or top view of jmy` improved machine; l

Figure 2, a View, in elevation, of-the same, as seen from the rear, with the connecting-bar n broken ,4

away

Figure 3, a similar view of the platform-sectionsfor rakes detached, showing the attitude assumed during loosely on an axle B,- with which they are' connected by suitable backingfratchets. A main frame, C, is mounted in proper bearings o the axle. l

The team is attached to a tongue, 1), projecting from said ame.

Anger-beam, F, is suspended from the main frame by a drag-bar, E, and coupling-arm E', of well-known'- construction, and is provided with the well-known Hussey cutting-apparatus.

A bevel-wheel, G, on the main axle, drives a corre sponding pinion, h, on a countershaft, h', carrying, on1

its front end, a wheel, I, having an external spurpinion, t, on one face, and an internal spur-wheel, vl', on'the other. The wheel I is'held on its shaft by a nut and screw, or equivalent fastening, so that it may readily be removed, reversed', and replaced.

The cutters are operated in the usual way, by a crank and pitman driven by a clank-shaft, J, carrying a small spur-pinion, j. v

This pinion, it will be observed, is so arranged as to gear with whichever of the pinions t' i is next to it.

The. internally-geared pinion i', being larger than the other, of course drives the cutters more rapidly when in gear with the pinion j. This feature, however, forms the subject-matter of 'an application led 'i simultaneously with this one, and is not, therefore, herein claimed.

A sprocket-wheel, K, on the main axle, drives, by means ot' a suitable chain, a corresponding pinion, l', on a shaft, k,- mounted in a bracket, C', projecting from the main frame. y

A bevel-pinion, t, on the shaft le, drives a corresponding pinion, k2, on a crank-shaft, k3.

A crank, on the shaft 7c3, reciprocates a slide-bar, L, by means ofv a pitman, and is thrown into or out known form.

vof gear by a shipping-lever, L', anda clutch of well- This slide-bar moves endwisetand parallel to the finger-beam, in suitable guides in the brackets M, which support the 1)latf 1'liisectioils.

Studs l, 2, on the slide-bar, act on double wipers n a', secured on the platform-sections, which are mounted in brackets M, in a'manner similar to that shown in my former patent above mentioned. The studs 1, 2, however, in this instance, are arranged in pairs, one on each side of the wiper, to reverse the movements thereof, as hereinafter mentioned.

Instead, however, of heilig connected directly with the finger-beam, as in my former patent above mentioned, the shafts N of the oscillating sections are mounted in bearings attached to a rockingbar,-O, to which the brackets M are likewise secured.

This bar is similar in construction to the rockingh bar of the dropper shown in my patent of June 30, 1868, No. 79,500, and is inserted in sockets o o, inthe usual well-known way, by which mode of attachment these parts can readily be removed or replaced.

Lugs m, on the brackets, extend forward under the finger-beam, and prevent the dropping of the rear end of the platform-sections. 'lo prevent improper vibration and twisting of the rear end of the sections, they are pivoted to a bar, n. y

The front end of an oscillatingv grating or clearer, It, is mounted in bearings on the divider or grain guardboard Q, while its rear end is supported by the bar n, which is bent up for that purpose.

A link, P, slotted, as shown in tig. 2, is connected atone end to a crank, p, on one of the shafts N.

A crank, lr, on the clearer, carries a friction-roller working in the slot o".

The operation ofthe machine is as follows:

The platfbrm-sections, ordinarily. are flat, with their teeth pointing toward the grain side of the machine, as in lig. 1.

When the crank-shaft lo is in gear, the sections N are successively quickly turned over toward the stubble-side of the machine, by the movement ofthe slide L toward the divider,'as in tig. 3, and the gavel is discharged behind the inner driying-wheel.

The movement of these 'sections is instantly reversed after thedischarge of the gavel, and each section, as,

it turns, clears its predecessor ot'what little grain has fallen during the discharge-movement. The grain thus accumulated is deposited by the last section on the clearer R.

As this movement takes place, the crank p traverses the slotted link P, over the roller ofthe crank r, until it enters the enlargement lr2 in the slot, which causes vthe clearers to rise and lift the gave] from the last The sections are stopped by` throwing `the shaft 7c out of gear, and they remain at rest until thc shatt is again thrown into gear, during which time the cut grain continues to fall upon lthe platform-sections, and the accumulated grain remains upon the clearer.

As soon as the shaft -ka comes into gear, the section next the clearer turns over toward the gearing-side of the platfbrm, sweeping the gavel from the clearer, and depositing it on the Vnext section, which in turn deposit-s on the next one, and so on in succession until gathering the. grain from each' section as it goes, and

deposit the whole on the ground. Y

It is obvious that a coupling-device might be attached automatically to stop and start the dischargingapparatus, such, for instance, as segmentgears, and that the details of construction of the devices shown n'iight be varied without departing from the spirit of my invention.

I am aware that oscillating platform-sections have been pivoted on a rocking-bar at their rear ends, so as to lift the front end of the platform-sections away4 from the linger-beam, and expressly disclaim such construction, as itinvolves the use of a cut-01T, and also the simultaneous lifting of the entire platform, both of' which disadvantages are ohviatedl by my improvement.

lVhat I claim as my invention, and desire to secure by Letters Patent, is

1. The relative arrangement, as set forth, of the finger-beam, the rocking-bar, the platform-sections, connected with the rocking-bar at their front ends only, and the supporting-brackets underl-.tpping Ybut not united to the finger-beam. 2. An oscillating grating or clearer on the divider side of the platform, in `combination with overlapping slatted platiu-m-sections, turning on aves. transverse to the finger-beam, as set forth. y

3. The combination of a vibrating clearer, with its adjacent platform-section operated by means of cranks and a slotted link, sul'xstantially as set forth.

4. The bar n, connecting the rear ends of the platform-sections with the clearer, as set forth.

5.- A vibrating grating or cleaning-rake, turning on `an axis transverse to the tinger-beam, and located at the divider-end of the platform, substantially in the manner described. V

In testimony4 whereof', I have hereunto subscribed my name.
